To all whom it may 007L067:

' Be it known that I, ARTHUR B. GLUNIEs, of

the city of Rochester, in the county of Monroe erence being bad to the accompanying drawlngs, formlng a part of this specification, and

to the reference-numerals marked thereon.

My presentinventio'n relates to grate structures especially adapted for use in connection with stoves and analogous devices, and has for its object the production of a structure of the under side of the locking member.

this character wherein the grate may be read-' ily inserted and effectively supported and in which the grate-bars carried by said grate may be securely locked in position to eliminate thepossibility' ofv displacement.

Other features of novelty and advantage will be hereinafter more fully explained, and pointed out in. the claims hereunto annexed. In the drawings, Figure 1 is a plan view of -a grate embodying my invention, parts being broken away for clearness in illustration. Fig. 2 is a sectional viewthereof, taken on the line 2 2 of Fig. 1. Fig. 3 is a similar view taken along the line 3 3 of v Fig. 1 and looking in'the direction of the arrows. Fig. 4 is a view showing the grate detached. Fig. 5 is an underneath view of the grate-supports. Fig. 6 is a detail view of the movable gratesupport. Fig. 7' is a similar view showing Fig. 8 is a detail View of the gratebar retainer. Fig. 9 is a fragmentary sectional view taken along the line 9 9 of Fig. 3; and Fig. 10 is a view of the supporting devices for the looking member viewed from beneath, parts being removed.

In the views the same numerals of reference designate similar'parts.

In the present embodiment of my invention, 1 designates a supporting casing or frame, either forming partlof the stove or an independent structure. This casing is" provided with'an aperture 2, and adjacent the periphery of this aperture are formed grate-supports 3-3,,a movable support 4 being also pro: vided in proximity to said aperture. The support 4' is preferably provided with an ex-v tension'5, adapted to be embraced by the'lugs 6 6, an abutment -7 being provided,again'st whichthe movable support rests while inposition, a recess 9 being provided thereon to receive said abutment. Projections 1O 10 may also be provided, if desired, for holding the movable support 4 in position.

pear.

Beneath the casing 1 is provided an abutment 12, the purpose of which will hereinafter more fully ap- 13 is an aperture formed in the casing 1,

and into this aperture is fitted a block 14. provided with a flange 15, adapted to restin a recess 16, pivoted lugs 17 17 being provided This block 14 when in the position shown in Fig.

for retaining said block in position.

3 will rest against a projection 18 upon the movable grate-support 4 to retain the latter: As motion in the-opposite direction is prevented by the abutment against movement.

the movable Support 4 will thus be securely locked in position. I

, In placing the grate in position the support 4 is removed and the grate placed upon the supports 3 3 from beneath. When in proper position, the movable support 4 is moved into position and the block .14 inserted into the aperture 13 in such a manner that said block will rest against the projection 18, after which f the retaining-lugs 17 17 may be turned to confinesaid block. I j v The grate in the present instance comprises a grate-frame 19 and grate-bars 20, the former ent embodiment comprising grate-bars having ournals 21 21, resting In recesses 1n one side of the grate-frame, and simllar ournals site side of the grate-frame.

22 22, resting in similar recesses at the oppo- Embracing the journals 21 21is a yoke 23, secured in any suitable manner to the grate-frame to retain said journals from displacement.

lars or members 24 24, between-and embrac- Th e jour-' nals 22 22 are each provided with thrust 001- ing which are the bearings25 25, carried by the grate-frame to prevent longitudinal motion of said grate-bars, and a retaining-yoke 26 is also provided embracing the journals 22 22 to prevent displacement thereof.

' Gearingor other power-transmitting mechanism. 27 is preferably interposed between the grate-bars 19 19, one of the journals22" extending through the slot 28 of the casing and being provided with a squared or other suitably-shaped portion to receive a wrench or the like for rotating said bars and swinging said grate in a horizontal plane.

To prevent displacement of the grate, the abutment 12 is provided, bearing upon the journals 21 21 at one side of the grate, the limited motion of the journals 22 in the aperture 28 being utilized to retain the grate in position at the opposite side.

Thus it will be seen that a grate structure is provided wherein the grate-frame will be securely held down by the grate-bars, which inturn are held in place by the overhanging edges or portions of the supporting-frame, which engage the ends or journals in such a Way that the grate may be rotated in a horizontal plane and grate-bars carried by the grate-frame revolved independently of one another. Moreover, as the abutment 12 is arranged at the rear of the grate-aperture and intermediately .ofthe movable and fixed supports, the grate in being swung into position with one side of the frame resting on the fixed supports will cause the rear journals of the grate-bars to engage this abutment from beneath, and when the movable support is locked in position the grate-bars and the frame on which they rest will be held from displacement.

I claim as my invention.-

1. In a stove, the combination Wit the case ing having supporting devices for supporting the rat at e Side, a a ra ada t to rest thereon, of a relatively movable support mou t n Ways on h a g opp t sa d supporting devices .and arranged to engage the grate to support it, and a locking device movable transversely of the ways for retaining the mova e s po n n a emen w the grate.

2. The combination with a stove having d upp s t er o an an additional surr rt able in e a o t t sa fix d supports, and arelatively fixed retaining-abutment located intermediately of the fixed and movable supports, of a grate embodying a frame adapted to rest upon said supports and arranged to be locked in position by the movable support, and havingmo'vable grate mem: bers thereon having portions adapted to engage said abutment when the grate is swung about the fixed supports to prevent the displacement of said movable grate members.
